FIELD: metallurgy.SUBSTANCE: invention relates to method and device for calibration of metal sections with two flanges located opposite each other, inner surfaces of which are spaced from each other by specified distance. Metal section is passed through device, which forms working solutions between two inner working rollers and two external support rollers. Said working rollers forming pair of internal working rollers are arranged to roll one over another to compensate acting on above pair of rollers on side of inner surfaces of flanges forming forces.EFFECT: using invention provides wear resistance, good weldability and resistance to brittle fracture of metal profiles.26 cl, 6 dwg |
